Does PVC have high hardness mechanical properties? The use of PVC sheets only achieves the goal of improving production efficiency, but also has the characteristics of improving land use efficiency, saving costs, fully utilizing mechanical efficiency.

1. What are the four major properties of PVC sheet?

(1) Mechanical properties

PVC has high hardness mechanical properties, which can increase with the increase of molecular weight decrease with the increase of temperature. The mechanical properties of hard PVC are much better than those of soft PVC.

(2) Thermal performance

PVC has poor heat resistance stability. It begins to decompose at 140 ° C its melting temperature is 160 ° C. PVC has a small coefficient of linear expansion is flame retardant.

(3) Electrical performance

PVC is a polymer with good electrical properties. Due to its greater polarity, its electrical insulation is as good as PP PE board.

(4) Environmental performance

PVC is resistant to organic solvents such as acid, alkali, salt, is more suitable for use as an anti-corrosion material in pharmaceutical chemicals.

2. PVC sheet waterproof film is a commonly used material in people's daily lives. The plastic sheet production line for PVC sheets uses plastic as the main raw material to produce plastic sheet production line equipment. Its raw materials include PVC, PP, PE, PC, etc.
